Biomechanics

Question 1

Biomechanics

Answer 1

Analyse and understand how forces affect movement and how to apply biomechanical principles to improve movement skills physical activity, sport and exercise.

Question 2

Force

Answer 2

Defined as a push of pull. It can produce movement or change the motion of an object.

Question 3

Mass

Answer 3

The amount of matter that makes up an object.

Question 4

Acceleration

Answer 4

The rate of change in velocity (speed).

Question 5

Velocity

Answer 5

Speed of an object in a given direction.

Question 6

Weight

Answer 6

The force that is exerted on an object or a body by gravity.

Question 7

Gravitational force

Answer 7

The force of attraction between two bodies or objects.

Question 8

Friction

Answer 8

A force that acts in the opposite direction to motion when two surfaces are in contact with one another. Less friction means higher velocity.

Question 9

Torgue

Answer 9

The turning effect produced by a force.

Question 10

Angular Motion

Answer 10

Movement of a body part around an axis of rotation. Involves the rotation around a central axis or a fixed point.

Question 11

Eccentric Force

Answer 11

A force that does not act through an objects centre of gravity.
